combustion engines andthe iment of the invention and GASKET i" i Thegasket shown in the drawing is adapt` ed for use in the manifold of aninternal combustion engine and it comprises a body4 7 formed from astrip of sheet metal or other i nuli by fianges lOwhich arepreferablyintegral with the body atthe edges `of the `openmnssms PVATENTOFFCEvieron, or "vnnsroiv, `"ILLINOIS, `Assrauoa j To vieron` MANUFAGrUnINeings.` `The flanges extend through the1openi i ings and the marginaledges thereof are bent,

over the adjacent portions of` the rings of i gasket material to clampthe ,rings in the auf` nuli. The flanges l0 reenforce the body andlprotect the gasket material from hot gasses j in the; openings.` Theouter `or marginal :walls of the `annuli are `flared outwardly whichleaves the outer `marginal edges ofthe gasketmaterial free. `When`the.gasket is clamped' between two partsof a manifold, for example, thepressure ismainly applied upon` the flanges to` form an `efoient seal atthe edges about the portopenings where seal-- ing is most desired and.most effective. flared outer marginal edges of the annuli Theyieldoutwardly upon compression and perj z mitthe gasket material tospread outwardly i aswell as toyield cross-sectionally and permittheinaximum clamping effect upon the flanged edges of the gasket abouttheopem ings. Thus,the gasket is capable of` yielding under compressionvtoenable the tightest` `clamping seal at edges of theopenings inf `steadof being distributed over" alarge area as has been customary and thisalso enables this material and prevent distortionduringhandlingandginstallation of the gasket I provide a continuous integralreenforcernent which extends substantially throughout the The annuliparts of,l

`clamping parts more readily than hereto- "96 k formed of lightmaterial` and to reenforce `15?.. and reenforcing ribs are formed inthese narrow seetions and are offset on the same face of the body as theannuli. These ribs, like the annuli, are in channel form as at 14 andthe ends of the channels o'f thev ribs merge with the channels of theannuli and form a continuous offset reenforcement on one face of thebody; The annuli-and ribs are located slightly. inward-:of the.peripheral edge of the body whereby an outwardly projecting fiange 15is formed in the plane of the sections 12 which cooperate'with theoutward flare ofthe-marginal edges ofthe annuli to facilitate yieldingupon compression of the gasket to insure clamping of the flanges aboutthe port openings to provide the seal at the openings. The ange 15projects in the plane ofi the faces of the parts between whichl thegasket is arranged and. provides a bearing surface which slides overthe' faces of the parts to expedite spreading ofthe marginal portionsofi-the gasketl and 'thisbearing surface prevents the flared walls ofthe'annuli fromdigging into the yface of the partV with which it'` iscontacted. Bolt openings 16 are provided in the sections 12 to receivethe boltswhich clamp the manifold parts together. f

T he'body ofthe gasket is provided with a substantially continuousreenforeement offset onjoneface thereof and thisreenforcementstrengthens the gasket and resists distortionfor stresses impressed onthe gasket are dissipated along .the length thereof rather than beinglocalized The gasket is additionally reenforced by flanges at the edgesofthe port openings as these'flanges are preferably integral with thebody of the gasket and engage the gasket material.

The -marginaledges'of the body yield under compression and are preventedfrom dig-- vgingV into thepart against which the edges areclampedvwherebyv the body is capable ofr spreading laterally ,as wellasyieldingfcrosssectionally under compression. The flanges about theport openings are tightly clamped "to provide an effective seal at theportion of the gasket where sealing is most desiredand most effective. l

I claim 1. I n a gasket, av body having openings` therein,channel=shaped annuli offset about said openings on one face of thebody,.and channel-shaped reenforcing ribs offset on the.l same faeeofthebody as the annuli and extending `between the annuliy and merging attheir-,ends with the annuli andforming aA continuous channel-shapedreenforcement about the body.

2. In a gasket, a body having openings therein, channel-shaped annulioffset about said openings on one face of the body, and

channel-shaped.reenforcing ribsoffset on the same face ofthe 'bodyas theannuli and eX- tending, between the annuli and merging at their endswith the annuli and forming a continuous channel-shaped reenforcement'about thebody'adjaeent the marginal edge thereof, said marginal edgeforming a flange projecting outwardly from said reenforcement in theAplane of the body.

3. In a gasket,'a body having openings therein, annuli about saidopenings and 0H- set on one face of the body and having out wardly4flaredl outer walls, rings of gasket' material in said annuli,reenforcing ribs olf-` set on said face ofthe body andextendingbetweeirand merging with said annuli to provide a v continuousreenforcement substantially coeXtensive with the body and increasing therigidity and preventing distortion of. said body, said ribs and theouter walls of said annulibeing disposed' inwardly of the edges' of. thebody toV provide an outwardly. extending marginal flange at. the edgeofthe body and disposed in thel plane` thereof, iianges at the edges ofsaidopenings and bentvover onto andconfined to the adjacent lportions ofsaid rings of gasket material, the

'whereby the flanges at the edge ofthe open-v ingsare tightly clamped-andprovide anzef'- fective seal for the edges of said openings.

t. In al gasket, a bodyl having openings' therein, annuli about:saidopenings and having outwardly flared outer walls, ringsof.l gasketmaterial insaid annuli, fianges at the edges of saidopenings and.- bentiover onto and confined to the adjacent portions of said rings of gasketmaterial,` the. outerr marginal edges of the gasket material being free,and; a marginal flange on ysaid body. and aboutithe flared walls of saidannuli to 1 facilitate spreadingy ofthe flared' walls andicross-seetional'compression offthe rings of gasketmaterial when pressureis appliedlto thegasket' whereby the flangesat the edges of the openingsare tightlyclamped and provide anfeffeetive seal at the edges of saidopenings JOHN H.
